In an exclusive sneak peek at Friday’s episode of Marriage Boot Camp: Reality Stars — Family Edition, the former Girls Next Door star participates in the “Deadly Departed” exercise, which stages the funeral of a loved one and forces a family member to confront how much they value the relationship when they still have the opportunity to fix it.

“They say you don’t know what you’ve got until it’s gone. And a prime example is realizing you’ve taken a loved one for granted after they’ve died,” explains Dr. V, who orchestrates the exercise alongside Dr. Ish. “Kendra, however, has such a deep-seated fear of her mother that even voicing her criticism out loud seems difficult for her.”

Standing beside a coffin, in which her mother pretends to be dead, Kendra begins reading the birthday card for Patti as she holds back the tears that begin to well up in her eyes.
